Python-Multipart is a streaming multipart parser for Python. Prior to version 0.0.22, a Path Traversal vulnerability exists when using non-default configuration options `UPLOAD_DIR` and `UPLOAD_KEEP_FILENAME=True`. An attacker can write uploaded files to arbitrary locations on the filesystem by crafting a malicious filename. Users should upgrade to version 0.0.22 to receive a patch or, as a workaround, avoid using `UPLOAD_KEEP_FILENAME=True` in project configurations.

The remote Ubuntu 22.04 LTS / 24.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-8027-1 advisory.

    It was discovered that Python-Multipart incorrectly handled certain

    regular expressions. An attacker could possibly use this issue to cause Python-Multipart to consume     excessive resources, leading to a regular

    expression denial of service. This issue only affected Ubuntu 22.04 LTS. (CVE-2024-24762)

    It was discovered that Python-Multipart did not properly sanitize line breaks during user input. An     attacker could use this issue to send

    arbitrary input, thus preventing other requests from being processed,

    resulting in a denial of service. This issue was only fixed in

    Ubuntu 24.04 LTS. (CVE-2024-53981)

    It was discovered that Python-Multipart was vulnerable to path traversal attacks. An attacker could     possibly craft and upload files outside the

    target directory, resulting in remote code execution. (CVE-2026-24486)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
